A wooden plank is inclined at and angle of 23 degrees above the horizontal. A 2.0 kg box attached to a rope is is pulled up the incline. The coefficient of kinetic friction between the box and the wooden plank is 0.15.
What does the tension in the rope is the box moves up the incline at a constant velocity?

Got it............. Im having problems knowing what the tension it is referring to actually is...

turingtest · Answer

...now let's do a little trig|dw:1329436980919:dw|we can use the force of gravity into the surface to find N, which we can use to find friction. we then have$$T-f-F_g\sin\theta=0$$along the direction of the incline, which we can use to find T.
